High-precision filtration with β≥200 and dual protection.

Technical Specifications

The PLF-C30×20P is a high-performance pressure line filter designed for reliable contamination control in automatic control, servo, and hydraulic systems. Engineered with imported glass fiber filter media, it delivers a filtration efficiency of η ≥ 99.5% and a filtration ratio of β₃, β₅, β₁₀, β₂₀ ≥ 200, ensuring precise removal of fine contaminants. With a rated flow of 30 L/min, working pressure up to 6.3 MPa, and 20 μm filtration rating, this filter combines compact construction, flexible installation, and dual protection to meet the most demanding system requirements. Tested in accordance with ISO16889-99 and GB/T18853-2002, it provides reliable, long-lasting performance across a wide range of industrial applications.

Key Features

· Compact Structure – More compact design and smaller footprint compared to conventional filters with

 equivalent flow capacity, ideal for space-constrained installations.

· Wide Pressure Application – Suitable for various pressure levels, offering versatility across different system 

requirements.

· Flexible Element Replacement – The filter element can be replaced in two ways depending on installation 

space:

  · Open the top cover and replace the element from above.

  · Unscrew the housing (drain oil first) and remove the element from below.

· Adjustable Flow Direction – If standard flow direction poses installation difficulties, simply remove the 

four screws

 on the cover and rotate it 180 degrees to reverse the medium flow direction, maximizing installation flexibility.

· Dual Protection System – Equipped with both a bypass valve and a differential pressure signaling device. 

When the filter element becomes contaminated and the inlet-outlet differential pressure reaches the preset

 value,

 the signaling device activates, indicating that the filter element must be replaced. This dual protection ensures

 system safety and reliability.

FAQ (Frequently Asked Questions)

Q1: What is the filtration rating of this filter?

A: The filtration rating is 20 μm, with a filtration ratio of β₃, β₅, β₁₀, β₂₀ ≥ 200 and filtration efficiency η ≥ 99.5%, 

ensuring reliable removal of fine contaminants from hydraulic systems.

Q2: What filter media is used, and what are its advantages?

A: The filter element uses imported glass fiber media, offering high filtration precision, strong oil flow capacity, 

low initial pressure loss, and high contaminant-holding capacity — extending service life and reducing

 maintenance frequency.

Q3: What is the maximum working pressure of this filter?

A: The filter is rated for a maximum working pressure of 6.3 MPa, making it suitable for a wide range of

 hydraulic system applications across different pressure levels.

Q4: What types of systems is this filter best suited for?

A: The PLF-C30×20P is ideal for:

· Automatic control systems – protecting sensitive control components

· Servo systems – ensuring clean oil supply for precise servo valve operation

· General hydraulic systems – providing reliable filtration across various pressure levels

Q5: How is the filter element replaced?

A: The filter element can be replaced in two ways, depending on installation space:

· From above – open the top cover and replace the element

· From below – unscrew the housing (drain oil first) and remove the element from underneath

This flexible design accommodates different installation configurations.

Q6: What if the standard flow direction does not fit my installation layout?

A: The flow direction is adjustable. Simply remove the four screws on the cover and rotate it 180 degrees 

to reverse the medium flow direction, providing maximum installation flexibility for space-constrained

 or complex piping layouts.

Q7: How does the filter protect the system from overpressure or clogging?

A: The filter features a dual protection system:

· Bypass valve – opens when differential pressure exceeds a preset limit, allowing flow to bypass the 

element and prevent system starvation

· Differential pressure signaling device – activates an alert when the element becomes contaminated,

 indicating that replacement is required

This dual protection ensures system safety and operational reliability.

Q8: What testing standards does this filter comply with?

A: The filter has been tested and certified in accordance with ISO16889-99 and GB/T18853-2002, 

ensuring international quality and performance standards are met.
